Oil Temperatures ?

tjlazer

What about when we reach 220 and we get some kind of limp mode where it bogs it down on launches? Is that just a myth or a defect on some of our 370Z's? When I get to 220 I notice a bad bogging off the line. I have to launch RPMs at 3K to beat a Civic.

Not a myth mines does it and there is a noticable difference in power after my oil temp gets over 180 ish or it could be the coolant temp either way yes the hotter the car runs the slower it gets . i have an oil cooler (25 row) and added a switch for the fan it performs way better than previously .

There are many things that will cause the ECU to reduce engine power (not necessarily limp mode). (Intake Air Temp, Water Temp, and Oil Temp are three of them.) It's very possible that you are hitting one of the others. IIRC, IAT is pretty low; somewhere around 85-90 F.

It would be nice if someone would post a list of params/values where the engine starts pulling power. IIRC, the limp mode values are in the FSM but I don't remember seeing anything on "low-power mode." If it's in the FSM, please point me to the right page(s). TIA.

I had the same problem. The Nissan dealer told me the car goes into safe mode at around 200+ degrees. There is no fix for this. It's built into the ECU. I had them install an oil cooler they recommended, $1100 dollars total. The car runs full power all the time now. The oil temp stays at around 180 in city traffic and around 160 on the hwy. This will also extend the life of your engine if you like to drive hard.

Safe mode is much higher than 200 degrees. Think about this- the oil needs to get higher than 212 degrees just to boil off any condensation. 200-220 is ok on this car. You'll see power loss from IATs, not oil temp. And you got boned on the oil cooler. First, you paid WAY too much for the unit and install, especially if it's the Nismo version without a thermostat. Labor was especially rapey. And if the oil is at 160 on the freeway, it's too cold. Cold oil is as bad as hot oil.

I'm picking nits and it doesn't affect your conclusion but you don't have to get to the boiling point of water for the water to evaporate. Granted, it will happen much faster and do a better job above boiling but lower temps will drive off water.

Eventually, yeah. Depending on the length of your commute. It'll take forever at 160 degrees.

A Nissan dealer told me convertibles are faster because they don't have a top.
If you want to learn about how to spend money go to a dealer.
